Does Bi-Amping with F5 for the lows and AlephJ for mid/high make sense?

Hi,

I have an AlephJ to drive my Klipsch RF-7's. I also have some boards of an F5 laying around. Would it make sensor to use those for bi-amplification to use for the low's and have some better control on those woofers? Or are their tonal characteristics to different?

Which version?
Here in the UK, bi-amping means using two amplifiers to drive the separate terminals of a passive crossover speaker.
Over in the US, bi-amping seems to mean building an active system where each amplifier is dedicated to a driver that is driven directly and the crossover is handled before the amplifying stages.

I would start with first option and later followed by option 2. We need to keep on building ) Thats the fun of this hobby

The thing that I'm considering all this is that I love the sound of the AlephJ but in the lows it just doesn't control these RF-7's. I tried the F5 which was good but in the end I preferred the AlephJ. now I was wondering if this could give me best of both......?

I've read that an X version of an Aleph has a perceptually better control of the lows.....so that could also be an option but it's something I do not fully understand if the damping factor is similar or even slightly higher. At least that's what I've read somewhere on the forum.

But then, when you go to active, the gains of the amplifiers are determined by the sensitivity of the speaker drivers.
You are likely to have at least 6dB gain difference and can approach 20dB of gain differences.
The two speaker driving philosophies are quite different: Bi-amping is not equivalent to active when considering the amplifiers required to drive the speakers.
